Chapter 6 Maintaining and Troubleshooting the TimeProvider

Diagnosing the External TPIU

4.Place the IMC in a static-free bag or on a static-free surface.

5.Insert another IMC into the shelf and tighten the captive screws.

Note: If the replacement IMC has a different software load than the original IMC, you cannot log in to the TimeProvider using the existing username and password. You must create a new username and password using the ENT-USER-SECUcommand.

6.Reload the IMC memory from the IOC by issuing the following command:

CPY-MEM:::::IOC,IMC,IMC;

Diagnosing the External TPIU

Table 6-4shows the function of the LED indicators on the front panel of the standalone TPIU.

Table 6-4. LED Conditions for the External TPIU

LED Name	Condition	Description

TPIU Power	Green	Interconnection cable is connected
	Off	Interconnection cable is disconnected or GPS input is
		disabled

Antenna Power	Green	TPIU is communicating with Antenna
	Red	TPIU has lost communication with Antenna
	Off	Interconnection cable is disconnected or GPS input is
		disabled

Antenna Signal	Green	Antenna is communicating with the TPIU
	Red	Master shelf is powering up or antenna is powering up
	Off	Antenna has lost communication with the TPIU

Diagnosing the Retimer Module

The Retimer module is transparent to framing errors, bipolar violations, and data errors; these errors are passed through to the downstream Network Element. If an incorrect signal type is inserted into the Retimer module (for example, if an E1 signal is connected into a T1 Retimer), the module may report a large slip count. Verify that the proper signal is inserted into the Retimer module.
